The Study
Genome-Wide Interaction Study of Dietary Intake and Colorectal Cancer Risk in the UK Biobank
This study looked at people who got colon cancer and compared them to people who didn’t, and checked if their eating habits and genes were different. It found some possible links, like maybe fish and a certain gene go together in people with cancer—but that doesn’t mean fish causes or prevents cancer. It’s like noticing that people who wear red socks often have headaches—you can’t say red socks cause headaches.

Quality score
Researchers compare people who have a condition (cases) with similar people who do not (controls), looking back in time for differences in exposure. Useful but more prone to bias.
Key takeaways
Summary
Based on the study abstract and findings.
- 1The fish gene effect is modest but meaningful — like getting a small protective shield if you have the right genes and eat fish often.
- 2Meat and alcohol risks are clear and consistent with known health advice.
- 3People with certain gene versions who ate fish more than twice a week had 15% lower cancer risk.
- 4Eating red or processed meat 3+ times a week raised risk by 16%.
- 5Alcohol 3+ times a week raised risk by 10%.
- 6Cheese and tea were linked to gene pathways that might help or hurt.

White British adults with certain genetic variants in the EPDR1 gene who eat fish more than twice a week have a 15% lower risk of colorectal cancer compared to those with the same variants who eat less fish.
White British adults who eat red meat three or more times per week have a 16% higher risk of developing colorectal cancer compared to those who eat less, and those who eat processed meat two or more times per week have the same increased risk, regardless of other lifestyle habits.
White British adults who drink alcohol three or more times per week have a 10% higher rate of colorectal cancer compared to those who drink less, even when accounting for smoking and body weight.
Milk consumption is linked to biological processes involving arginine ADP-ribosyltransferase activity, specifically through ART family genes, which are connected to the growth and metabolic changes in colon cancer.
Tea consumption is associated with biological processes related to keratinization and intermediate filament formation that are linked to the anti-cancer properties of epigallocatechin-3-gallate, a compound in green tea.
